Resumen inglés | For the family of degree at most 2 polynomial self-maps of C3 with nowhere vanishing Jacobian determinant, we give the following
classification: for any such map f, it is affinely conjugate to one of the following maps: (i) An affine automorphism; (ii) An elementary polynomial autormorphism E(x, y, z) = (P(y, z) + ax, Q(z) + by, cz + d), where P and Q are polynomials with max{deg(P), deg(Q)} = 2 and abc ≠ 0. (iii) ì H1(x, y, z) = (P(x, z) + ay, Q(z) + x, cz + d) ï H2(x, y, z) = (P(y, z) + ax, Q(y) + bz, y) í H3(x, y, z) = (P(x, z) + ay, Q(x) + z, x) ï H4(x, y, z) = (P(x, y) + az, Q(y) + x, y) î H5(x, y, z) = (P(x, y) + az, Q(x) + by, x) where P and Q are polynomials with max{deg(P), deg(Q)} = 2 and abc ≠ 0. |
